onsemi Single Bipolar Transistors BU406

The BU406 is an NPN silicon power transistor designed for horizontal deflection output stages in TV and CRT applications. It is packaged in a TO-220AB case and rated for a collector-emitter voltage of 200 Vdc, a continuous collector current of 7 Adc, and a total device dissipation of 60 W at 25 °C. The device features a maximum collector-emitter saturation voltage of 1 Vdc at 5 A collector current and 0.5 A base current, a current-gain bandwidth product of 10 MHz, and a thermal resistance from junction to case of 2.08 °C/W. It is Pb-free and RoHS compliant.
